Remote code execution via SDP format overflow
Published Mar 13, 2023 · Updated Mar 3, 2025
Memory corruption in Samsung Exynos baseband chipsets allows remote attackers to execute code via malformed SDP during call setup. The SDP parser copies more than 12 accept-type format entries into a fixed-size buffer without checking the entry count, corrupting memory. A victim's phone number is sufficient and no user interaction is required; exploitation compromises the baseband and can also interrupt service.
